Authenticator : 2FA & OTP

Scan a QR code to add 2FA accounts and generate verification codes offline. Import, transfer, and restore tokens with encrypted backup for easier account access.

Authenticator App is a two-factor authentication tool that generates one-time verification codes for websites and services supporting the TOTP or HOTP standards.

Scan a QR code or enter a secret key manually to add an account. Verification codes are generated locally on your device and remain available without a continuous internet connection, making it easier to access email, social, work, developer, gaming, and other supported online accounts.

KEY FEATURES

• TOTP and HOTP Codes

Generate time-based one-time passwords and counter-based one-time passwords according to each account’s authentication settings.

• QR Code Setup

Scan the QR code displayed by a website or service to quickly add its authentication information.

• Manual Key Entry

Add an account manually when a QR code is unavailable or cannot be scanned.

• Offline Code Generation

Generate verification codes directly on your device, even when an internet or mobile network connection is unavailable.

• Multiple Account Management

Keep authentication codes from different websites and services together in one organized account list.

• Authenticator Account Import

Import compatible QR-based authentication data to move existing accounts into the app.

• Device-to-Device Transfer

Create a transfer QR code and move authentication accounts between supported devices without setting up every account again.

• Encrypted Backup and Restore

Export authentication accounts to an encrypted backup file and restore them after reinstalling the app or moving to a new device.

• Local Data Storage

Authentication secrets and verification codes are stored locally by default and are not automatically uploaded to third-party servers.

HOW TO SET UP 2FA

1. Open the security settings of the website or service

3. Scan the displayed QR code with this app
4. Enter the generated code when signing in

You can also enter the provided secret key manually when QR code scanning is unavailable.

IMPORTANT SECURITY INFORMATION

Authentication data is sensitive. Keep your device passcode, recovery codes, backup files, and backup password in a secure location. Never share QR codes, secret keys, or active verification codes with other people.

An authenticator app does not replace the account recovery options provided by each website or service. After enabling two-factor authentication, save the recovery codes supplied by that service so you can regain access if your device or authentication data becomes unavailable.
